Time division multiplexing communication system, time division multiplexing communication switch system, and communication control method of a communication system

摘要

A communication system includes communication devices; a switch device having coaxial terminal units to which the communication device are connected, a switch unit of entirely or individually connecting the coaxial terminal units, and a switch control unit of controlling the connection status of the switch unit; and a transmittal right control device. The transmittal right control device is connected to the terminal, and manages the connection status of the switch unit, receives from the communication devices requests for time for communication with other communication devices, determines assignment of time for communications between the communication devices, notifies the communication devices of the assignment, and instructs the switch control unit not to make signals interfere among the communication devices in different combinations for communications in the same time period.
